It’s not just “puppy eyes”...it’s biology. 👀🐾 Puppies (and humans!) are born with eyes that are nearly full-sized, which is why they always look so big and expressive. Their eyeballs only grow a little in those first few months and then stop, even while the rest of their body keeps growing. This baby-like proportion is called neoteny, and it’s nature’s way of keeping us obsessed. Those big eyes literally trigger the same caregiving response that human babies do. 🥹❤️ #PuppyFacts #ScienceOfCute
